Lol an antenna trailing out of a plane? Many safety issues with that. Don't the antenna systems on planes work just fine? You can be sure that the military have the best options available with their endless funding.
I can't believe what we are hearing from the good ol' USA now. Disbanding police forces?????? Then replacing them with some "unarmed" peaceful group, which some would like to call "social workers".
All l can say is ROFLMAO.
I foresee a complete breakdown of law & order.
So if a dude is running around killing people with a gun, they will send in this peaceful unarmed group to talk to him??????

I'd say that's a pretty good analysis of the case--with the understanding that I have no legal experience of any kind other than being excused from a jury for telling the prosecutor what I thought of her. I think there's a pretty good chance of convicting him of Murder 3 (reckless and wanton disregard for human life) without having to go as low as manslaughter (simple negligence leading to death), but for Murder 2 they need to prove a specific intent to kill, and I'm not sure they can. I'm pretty sure the three henchmen are going to slip the aiding-and-abetting charges, too. All in all, a disappointing situation; but then, politicians and media love riots--politicians because it usually results in more power for them, media because it makes for exciting headlines (some of the headlines, of course, made by politicians virtue-signaling about how much they hate riots).
So here's a question about ham radio. Suppose I were to go up in a small airplane, say to an altitude of 2000m or so. Suppose I had a...

I used to use a Pi to run the shack, until I tried to install WSJTX (this was a few years back now), which proved very difficult at the time. In order to get up and running I substituted the Pi for one of my laptops. Not only was this much faster, it was also a lot easier to update software (for me anyway) and a lot more flexible.
I now have a tower, with 2 monitors, running Windows 10.
Kind regards,

I’m running an FT-897D for FTI, using a SignaLink interface. The Data out goes to the SignaLink and the CAT goes to the computer.
There are generally helpful videos for most radios on YouTube.

Hi from UK.
If you have the radio bug then a ham license will give you many hours enjoyment. You get to talk to like minded guys. Then you learn more. That leads to the "burning desire" to get a bigger & better radio. Then a bigger & better antenna.
So it's a hobby that grows with you.
First place to start is to find out what material you need to study to get the Tech license. I can't help you there as it's different in UK.
But once you have done the study & booked your exam (online exams are now available), you can start talking to hams & you will soon find your path.

I had to look up that cable. I think you only have audio there. You need the USB connection for CAT control.The only Yaesu I own is the 991a and it uses a USB cable for everything. A quick search reveals you also need a USB to serial cable to control the radio in addition to the DC11F.

Ah, l thought the very same. No way could they make a murder charge stick. Especially considering that the cop was fully aware that he was being filmed by bystanders.
It's also been mentioned on our news that the victim had Covid. Therefore the defense will most certainly argue that his breathing difficulties were due to the virus. They will also argue that the officer had restrained suspects in the same manner throughout his career & this was the only fatality. No doubt the defense will put police training under the microscope, and also the many cases where suspects have been restrained in the same manner by police forces nationwide & internationally which did not result in fatalities.
I am not a solicitor & l, like yourself, can already see cracks in those charges.
Yes you are right. After the jury let that cop walk, the riots will resume with more aggression than we have seen so far. They will also be careful to ensure the jury is 50/50. But after the cop walks, they will argue that the jury...

It depends on the location. At least in the US, the riots are almost exclusively a liberal-on-liberal phenomenon. Liberals—especially urban liberals—tend not to have guns, because they depend on police to protect them. (Until they defund the police, of course.) Some of them try to defend their businesses, mostly either in an unarmed fashion or with ineffective weapons, but others depend on luck or expressions of solidarity with the rioters.
Folks in smaller cities, villages, and rural locations have police forces that are smaller, less well-trained and -equipped, and even sometimes an hour or more away. They can’t depend on police to protect them, and their mindset is more generally individualistic anyway. They’d be more likely to defend their businesses with lethal force, except that for the most part their businesses are not in danger. Antifa is safest in cities that have been run by liberals for decades.
This isn’t to say that conservatives don’t have their problems or that they can’t be equally...

Hi again Neil,
I am 10yrs ahead of you & now retired. I was a registered nurse for 30yrs.
Then decided l needed a change so l used those City & Guilds in electronics qualifications to enter the electronics industry. The intention was only for a temp job after moving from Scarborough to Nottingham.
But l found that l enjoyed the work. And it also helped when my employers realised my talents & l moved from doing the repairs to testing the other repair guys work. They even bumped up my pay above the rest.
Then one of my mates let slip my previous occupation. What happened then was guys who were unlucky enough to sustain an injury came to me rather than a first aider. That pissed off the company. But their solution was to send me on a first aiders course for a week. Hell they even provided me with a brand new hire car for the week as l was not permitted to use my own car on company business. Then the defib course, the oxygen administration course. So perhaps understandable that l stayed for a few...

Hi All,
I am new to HAM radio world. I need a new hobby, and radios have intrigued me for some time. I am interested in getting my HAM licence and learning more! I am in the Sacramento, CA area!
Thanks,
TtT

Hi Gene - sorry for the late response. You'll be fine. I can't imagine you'd have interference. I think just the opposite would be the case because the metal would be an extra shield. Very fortunate for you to have such an easy route.

I knew of a club in the southern portion of TEXAS that was a school club, their students were mostly Latinos and Anglo's and were very poor.
They had no budget and their instructor was looking for anything he could use to help them get their start.
I will try to see if I can find their QSL Card in my files.
Those people were very deserving and would have appreciated anything you could possibly send them! I think their call was K5LBJ

In the life of a ham, in the beginning, a person owns no equipment, or at the very least, they have a relative or a friend that gives them some equipment to get their start.
As their amateur radio career begins, they accumulate a lot of junk and a little good stuff.
As times goes by you make friends, your friends also has a laundry list of junk which gets traded, bought, sold back and forth until finally all of your friends are dead and you are the last remaining soul.
As long as you make friends and have friends you always have a venue for your used radio equipment.
Your mom would be well aware of who your dad's friends were and how they helped him thru the years.
Usually those people will come forward and make remarks about how they were friends and how they would like to have this, that or the other. The best thing you can do is ask your mom - was this guy / gal really dad's friend.. Did they ever offer to help him, or were they only his friend when they wanted something?

That's a nice little handy you have. Mine is a few years old now (VX-8).
In UK, the equiv exam to the tech is the "Foundation". However, many in the UK sit that exam & never bother with the rest. Reason = with a Foundation license they can use "all" ham bands. The only restriction is that their power is limited to 10w. The next licence up (Intermediate) the power is restricted to 50w.
Then the top licence permits full power of ofcourse.
Having said that it would very difficult to police how much power anyone was using

I woudl not say you have made an error / wrong assumption when it comes in connecting serial / parallel LED array.
You are just working what is known / given , same as I.
This whole exercise did not started as theoretical application of Ohmís law, but as an experiment with real limitations, including wallwart DC supply.
I need to point out that the specification for the LED is not written in stone, just my best guess.
I really do not have real data what is maximum current before LED became "fast blow fuse".
Here is the latest.
With the fan running @13V , drawing 55mA I added 100 Ohms limiting resistor connected to 3 LED's in series.

Admittedly, i made two critical errors in my first response. The first error was suggesting a single resistor for the entire array. Diodes in parallel to other diodes have the strange ability to unevenly pass current. This means every parallel path of LED lights will need an individual limiting resistor. The other error i made was making the assumption your supply was regulated. Being it is typical for wall worts to be rectified sine waves with no regulation, the unloaded peak voltage and the loaded RMS voltage prior to rectification will be different ~ hence the 16v you see with nothing connected
This needs to be taken into consideration when designing the system.

I believe both are true. The newer FT-400, FT-3 and FTM-100 an FT-2D with latest firmware can go into HRI mode and make a direct connection. They can also provide a node access where you can use another mobile Fusion capable radio to connect. I use a FTM-100 in my pickup and can hit my FTM-400 from cross town similar to a repeater and connect to Fusion via the FTM-400 and PC internet connection.
I hope this helps.

I realize I am getting ahead and answering / posting before my posts are approved.
I run another test to get better feel for the DC supply.
My ultimate goal is to pass air over the array.
I am currently using 12V DC fan and the DC supply output drops to steady 13V @ 55mA
I think I will size the limiting resistor to pass 150 mA to the array.
